3.32 Fault Code F63: Slide Shutter Fault
Symptom:
If this fault is registered, the program is not interrupted. The fault will only be
indicated when the fault code memory is checked in the service mode.
Background information: Even though the slide shutter motor has been
activated, there is no signal change at the position switch. The slide shutter
motor will be activated again whenever repositioning is required.
Cause:
Position switch defective.
Remedy:
Replace the circulation pump. See Section 050-4.13.
Cause:
Connection wires open- or short-circuited.
Remedy:
Check the connection wires for continuity.
Cause:
Drive (synchronous motor) defective.
Remedy:
Replace the drive. See Section 050-4.16.
Cause:
Slide shutter gearing defective.
Remedy:
1. Check to see if water is alternating between the upper/lower spray arms
and the middle spray arm. This can be done by removing the side panels,
selecting a wash program and observing the water flow between the
upper spray arm and middle spray arm water paths. If the water flow is
alternating, go to Step 2a below. If not, go to Step 2b.
2. Check position switch B3/12 at connection ST14 (using a multimeter) for
low DC pulses at 30-second intervals.
1. If pulses are present, the electronic needs to be replaced. See
Section 100-4.5 or 100-4.6.
2. If pulses are not present, first check wire connections for an open or
short circuit. Replace the slide shutter drive, if necessary. See Section
050-4.15.

Symptom:
